The Club that made this comment needs to catch up with discrimination laws. Danny Rose, the Tottenham and England footballer, has been open about his struggles with depression but, as he points out, it doesn't affect his abilities on the field.
Since 2010 the Equality Act has prohibited employers asking recruits about their health, except for a limited number of reasons. It was felt that many disabled people, especially those suffering with mental health issues, were put off applying for jobs because of these pre-employment questions
One of the few occasions when a potential employer can ask a health question is to establish whether the candidate will be able to carry out a function that is intrinsic to the job. For instance, to find out if someone applying for a job in a warehouse will be able to do heavy lifting.
Trying to find out if someone is 'crazy' is not a valid question and the club involved is lucky Danny Rose didn't take this any further.
